I'm trying to get the file names in a folder that end in a specific way (100MVC.otb+). AFAIK the way to do this is like this:

signals=dir(fullfile(signalDir,'*100MVC.otb+'));

But for some reason it seems like it can't understand the wildcard and it never finds a match. The same happens when I try to list the files:

>> ls(fullfile(signalDir,'*100MVC.otb+'))
No matches for pattern 'Test02_20200522\*100MVC.otb+'.

Any idea why it's not working, or how to solve it?

I mocked up a folder inside my current directory named "Test02_20200522" with contents "file1_100MVC.otb+" to "file4_100MVC.otb+".

Your code works so long as I don't change my current directory. When I do, it can no longer find the folder and returns the same error message you are seeing. To avoid this, I recommend using the full path name for signalDir, not just the final folder name.
